New with tag Strip Cut Crochet Fabric 90% Nylon, 10% Spandex High Waist Fit Moderate Bottom Coverage Swimwear fabrics often include nylon, spandex, and lycra which are durable, yet when exposed to harsh sunlight, chlorine, or hot tubs over-time can become compromised. To keep your bikini looking fresh all summer, after your fun day in the sun, rinse your swimwear by hand in lukewarm water with a mild soap or specialty detergent. Lay flat in a single layer to dry. DO NOT lay garments on light colors, tumble dry, iron or dry clean. Last but not least, all you bronzing babes out there, keep in mind that tanning products and lotions/oils can damage swimwear fabric, we recommend washing your bikini immediately after use.
